You know the sting of a campaign that never reached its audience. Maybe you watched opens lag or saw clicks fall short. That feeling stays with you because every missed message is a missed chance to grow.
This guide fixes that by using recent inbox placement data, not guesswork. ActiveCampaign hit 94.2% in Jan 2024 tests, MailerLite led the five-round average at 94.41%, and GetResponse posted 90.9% in the latest round. The multi-round overall average slid to 83.1%, which means about 16.9% of messages can go missing without the right setup.
We evaluate each platform on deliverability, automation, segmentation, and infrastructure. You’ll get clear advice so your campaigns enter more inboxes. When a tool matches your audience and content, we call it out.

Key Takeaways
- We prioritize inbox placement data over opinion to find the best email tools.
- Top services like ActiveCampaign and MailerLite consistently outperformed averages.
- Authentication (SPF, DKIM, DMARC) moves more messages past Gmail’s Promotions tab.
- Different ISPs treat messages differently; plan domain and IP strategy accordingly.
- Try GetResponse with a Free 30-day trial to validate deliverability on your list.
Why deliverability should drive your choice right now
Choose tools that get your messages seen — that single choice moves revenue more than design tweaks. A correctly delivered email lands in the inbox, including tabs like Gmail Promotions. The latest cross-ESP average sits at 83.1%, which means 16.9% of emails never reach subscribers.
What this means for your ROI:
- Your goal is simple: more email seen by more subscribers, because inbox placement compounds opens, clicks, and revenue across campaigns.
- Every percentage point above the 83.1% average translates into measurable sales and lower acquisition costs.
- Set a target near the “excellent” threshold (>89%) and monitor weekly cohort trends to catch issues early.
Choose a service that supports authentication, complaint handling, and fast access to deliverability experts. Focus your first month on clean acquisition, list hygiene, and engagement to give mailbox providers clear positive signals.

Email Marketing Platforms for High Deliverability: how we evaluate
We rate each service by how quickly you can prove your identity to inboxes and remove problem addresses. That first minute of setup often predicts whether your sends land where they belong.
Core checks
- Authentication speed: SPF, DKIM, and DMARC setup and domain guidance.
- Complaint handling: feedback loops and automated suppression of complainers.
- Access to experts: live troubleshooting and deliverability documentation.
Infrastructure and reputation
Shared versus dedicated IPs shape early sender reputation. We score how each service manages pooled reputation and whether it offers easy IP upgrades.
Automation and content controls
Strong segmentation, behavior-triggered flows, and spam-testing tools lift engagement metrics and reduce filter flags. Look for link-domain options, image-to-text balance checks, and integration with inbox testing tools.
| Criterion | Why it matters | What we check |
|---|---|---|
| Authentication | Validates sender and reduces Promotions placement | SPF/DKIM/DMARC setup time, domain guidance |
| Complaint handling | Removes risky recipients and protects sender reputation | Feedback loop support, automated suppression |
| IP & infrastructure | Pooled reputation affects new senders | Shared vs dedicated options, warm-up support |
| Automation & content | Targets engaged users and avoids spam filters | Segmentation, spam tests, tracking domain controls |
| Monitoring & logs | Speeds diagnosis and fixes | Delivery logs, postmaster tool integrations |

What recent testing shows about inbox placement in the present
Recent inbox tests expose where messages actually land and why that matters to your campaigns.
The headline: the cross-provider average sits at 83.1%. That means a sizable share of sends never reach primary views. This gap hits opens, clicks, and revenue.
Top performers held strong. ActiveCampaign hit 94.2% in Jan 2024. Mailer Lite leads a five-round average at 94.41%. GetResponse recorded 90.9% in Jan 2024.
Key patterns to watch
- Authentication cuts Promotions placement when SPF, DKIM, and DMARC are set.
- Microsoft applies stricter filtering for some senders; expect month-to-month swings.
- Shared IP tests used seed lists and equalized content; historical volatility remains.
| Provider | Latest round | Notes |
|---|---|---|
| ActiveCampaign | 94.2% | Strong recent peak, occasional fluctuation |
| Mailer Lite | 89.8% (Jan), 94.41% avg | Most consistent across rounds |
| GetResponse | 90.9% | Balanced across Gmail, Microsoft, Yahoo, AOL |

ISP realities: Gmail, Microsoft, Yahoo, and AOL differences you can’t ignore
ISPs don’t treat every send the same. Gmail often delivers but sorts messages between Primary and Promotions. That split isn’t a total failure. Promotions can still drive opens when subscribers expect commercial content there.
Why Gmail Primary vs Promotions isn’t binary success/failure
Authentication matters. In Jan 2024 tests, full DMARC plus SPF and DKIM cut Promotions placement. Set auth early to improve inbox prominence.
Microsoft filtering nuances and how platforms vary there
Microsoft applies stricter filters and shows more month-to-month swings. Some services stayed clear of spam tags; others struggled.
- Use seedlists to map where your emails landing differs by ISP.
- Throttle and warm up when you ramp volume, especially to Microsoft domains.
- Monitor sender reputation, complaints, and blacklists monthly.
- Validate segment-level placement at scale with a GetResponse Free 30-day trial — https://www.getresponse.com/?a=MacDnqpGmR — and build an ISP playbook from those results.
| ISP | Behavior | Practical action |
|---|---|---|
| Gmail | Primary vs Promotions sorting | Authenticate (SPF/DKIM/DMARC) and test content |
| Microsoft | Stricter, variable filtering | Warm-up, subdomains, and seedlist tests |
| Yahoo/AOL | Generally friendlier but variable | Monitor trends and blacklist status |
Pricing, free plans, and send limits that affect deliverability outcomes
Free plans often carry hidden constraints that affect how your sends perform in inboxes. Caps change the pace you can ramp and the safety of each campaign. Review limits before you commit to a service or plan.
Daily vs monthly caps: real scenarios
Example: Brevo lets you send 300 emails day on its free tier. AWeber’s free allowance equals 3,000 emails month for 500 contacts.
Daily caps like 300 emails/day and monthly caps like 3,000 emails/month shape warm-up and cadence strategy. Use them to plan steady ramps rather than sudden spikes.
List size vs email volume: avoid reputation hits
Large contact counts do not guarantee good outcomes. If engagement falls, your sender reputation drops quickly—especially on shared IPs.
Practical checks:
- Stagger sends by timezone and segment to smooth volume.
- Align frequency to subscriber behavior to keep engagement positive.
- Use pre-send spam checks and confirm link/domain alignment to reduce false positives.
| Constraint | What to watch | Action |
|---|---|---|
| 300 emails/day | Limits rapid scaling | Use phased ramping and split sends by segment |
| 3,000 emails/month | Can restrict campaigns in a month | Prioritize high-value sends and schedule promotional bursts |
| High contact caps | Risk of low engagement | Segment and clean lists before large sends |
| Shared IP pools | Pool health affects your rates | Consider dedicated IP only when volume and consistency justify it |
Monthly monitoring matters. Track complaint, bounce, and block metrics each month so you can act early. Build a simple escalation plan that outlines how to ramp volume safely after each successful sprint.

Tools that help you monitor and improve deliverability continuously
Use a mix of inbox tests and reputation checks to turn guesses into measurable actions. Start with tools that show where your emails landing and which technical signals need fixing. Run tests monthly and treat results as directional, not absolute.
Inbox placement testing and spam checks
GlockApps offers seedlist-based inbox placement, spam scoring, and auth checks. Unspam.email adds AI heatmaps, previews, and detailed spam triggers. Use either to spot risky content and tab routing across Gmail, Microsoft, Yahoo, and AOL.
Reputation and authentication monitoring

- Validate tool recommendations with live sends via a GetResponse Free 30-day trial to confirm real-world rates.
| Tool | Primary use | Action |
|---|---|---|
| GlockApps / Unspam.email | Inbox tests & spam checks | Identify content and tabing issues |
| Mailgun Optimize | Reputation & blocklist monitoring | Alert on traps and IP issues |
| ZeroBounce / MxToolbox | Validation & DNS/blacklist checks | Clean list and fix DNS records |
Pro tips to keep emails landing in inboxes
A few technical steps and steady habits protect your sender reputation more than fancy templates. Apply a short checklist before big sends and treat each change as a testable hypothesis.
Authenticate: SPF, DKIM, DMARC, and subdomain strategy
Authenticate and isolate
Set SPF, DKIM, and DMARC on your sending domain. Route promotional sends through a subdomain to isolate reputation.
Why it matters: tests show fewer Promotions placements when auth is correct. Verify DNS records and publish a policy that matches your sending patterns.
Warm-up, cadence, and segmentation
Warm up new IPs or domains slowly. Keep a steady cadence tied to engagement. Segment by recency and interest so content stays relevant and opens remain strong.
List hygiene and suppression
Validate addresses before campaigns and remove inactives before large blasts. Suppress bounces and complainers quickly to protect rates and sender reputation.
- Keep image-to-text and link ratios balanced and align tracking domains with your brand.
- Monitor bounces, complaints, and blocks after each send and remediate fast.
- Run spam-score and render tests, then adjust copy and layout by ISP.
Make sure every major send follows a pre-launch checklist with auth, seedlist tests, and list checks. Measure improvements over a month with a GetResponse Free 30-day
| Action | Quick benefit | Check |
|---|---|---|
| Authenticate domain | Fewer tab placements | SPF/DKIM/DMARC present |
| Warm-up & cadence | Steady ISP trust | Volume ramp plan |
| Validate & suppress | Lower bounces/complaints | Clean list export |
Conclusion
Landing in the inbox is the single action that multiplies every campaign’s return. The cross-provider average of 83.1% leaves clear upside. Leaders like ActiveCampaign (94.2%), MailerLite (94.41% five-round avg), and GetResponse (90.9%) show what’s possible when technical setup and cadence align.
Practical steps: verify authentication, keep list hygiene strict, and test by ISP and segment. Use tools such as GlockApps, Unspam.email, and MxToolbox to spot problems fast.
